Quantum Light Instruments Lasers

QLI LogoQuantum Light Instruments, Ltd. specializes in EO Q-switched diode-pumped solid-state lasers optimized to operate at low pulse repetition rates with moderate pulse energies (up to 120 mJ and 200 Hz repetition rate).

Quantum Light Instruments, Ltd. is a market-driven company. We listen to what our customers are saying and do our best to deliver solutions that meet and exceed expectations. No request is too small. Therefore, we are happy to respond to all inquiries and will provide our best support for your needs.

Our key innovation is the water-free laser crystal cooling technology, combined with laser diode end-pumping. This combination resulted in a high energy, compact, single box, user-friendly turnkey laser, requiring little to no maintenance. QLI has over 50 years of combined experience in the development of sophisticated high energy DPSS Lasers and non-linear wavelength conversion devices. Our highly skilled staff are able to tailor solutions to meet your application needs.

Q-TUNE Series

Q-TUNE-IR

The Q-TUNE series is a high energy, compact, tunable wavelength laser consisting of an Optical Parametric Oscillator (OPO) capable of producing a tunable wavelength range of 410-2300 nm with a linewidth narrower than 6 cm-1. Optional second harmonic generator extends the tuning range to 210-410 nm.
The combination of a pulse duration shorter than 5ns and an upper repetition rate of 100Hz, makes the Q-TUNE a perfect coherent light source for temporally resolved spectroscopy, metrology, photo-acoustic imaging and remote sensing applications.

Q-TUNE-IR Series

Q-TUNE-IR The Q-TUNE-IR uses an Optical Parametric Oscillator (OPO) to produce tunable wavelength in 1380 – 4500 nm range with a linewidth less than 10 cm-1, achieving > 6.5mJ of pulse energy @ 3500nm for the F-10 configuration (> 2mJ @ 3500nm for C-10) with a 10Hz repetition rate. A broadband version with linewidth up to 200 cm-1 is also available by request.  The Q-TUNE-IR requires little maintenance, with all laser electronics integrated into the housing, including an air-cooling system, eliminating the need for chillers, or large power supplies, all while providing a guaranteed pump diode lifetime greater than 2 giga-shots.

Q-SHIFT Series

Q-Shift SeriesThe Quantas-Q-SHIFT series is a family of Q-switched DPSS lasers featuring a built‑in nonlinear wavelength conversion stage, allowing the production of wavelengths that are not accessible with conventional solid-state laser sources, including 1163, 1177, 1300, 1317, 1551 and 1571nm. An optional harmonics generator is also available for for the Q-SHIFT, allowing generation of up to the 4th harmonic for each fundamental wavelength.

Q-Spark

Quantas-Q-SPARK-266: High energy, compact, nanosecond, DPSS laser

The Q-SPARK series, from Quantum Light Instruments Ltd., features a short <1.5 ns pulse with pulse energies up to 10 mJ. Due to the short cavity design, pulse durations of <800ps are achievable with pulse energies up to 5mJ. The innovative water-free laser crystal end-pumping technology produces a Gaussian-like, low divergence, high peak power laser beam in compact, air-cooled package.

Q1 Series

Quantas-Q1-211: High energy, compact, nanosecond, DPSS laser

The Q1 series is a compact, energy-efficient, diode pumped, air-cooled, Q-switched laser available at 1064 and 1053nm with up to 45 mJ of pulse energy and rep rates up to 50Hz.

The innovative laser design has resulted in a user-friendly, turnkey system that requires little maintenance.

Q2 Series

Quantas Q2 QLI

The Q2 series is a versatile, diode pumped, air-cooled, Q-switched laser capable of achieving up to 80mJ of pulse energy with an operational rep rate up to 100Hz. Available at the fundamental wavelengths of 1064 and 1053nm, the innovative water-free laser crystal end-pumping technology produces Gaussian-like, low divergence laser beams with high peak powers, enabling efficient harmonics conversion through the 5th harmonic.

Q2HE Series

Quantas-Q2HE-211: High energy, compact, nanosecond, DPSS laser

The Q2HE series, from Quantum Light Instruments Ltd., features an innovative water-free laser crystal cooling technology that enables generation of high quality laser beams with up to 100 mJ pulse energy and/or up to 4 W of average output power. Featuring a pulse duration of less than 7 ns and a low beam divergence, the Q2HE is capable of achieving efficient fundamental wavelength conversion through the 5th harmonics of 213/211 nm.
